I’m looking to install an Iotawatt across 11-12 circuits in a sub board that’s very tight on space.
There’s an 80A main breaker and a bunch sub circuits for lights (2x10A), power (3x16A), air conditioning (3x16A), oven (1x16A) and a shed (1x20A). Typical consumption is 200kWh/month in winter and 500kWh in summer. Typical maximum load would be 7-10 kVA with all the air-conditioning, oven, lights and appliances running simultaneously.
I’m planning on installing a 50A for the mains, the air conditioning group (4.8kW), and one for a future 5kW solar install. Is there a recommended 10/20A compact CT for the other sub circuits? I’m happy to solder up leads and jacks.
I’d like to monitor each of separately, but I’m not sure there will be space for 12 CTs n the board. Apart from grouping circuits, are there any other space saving tricks?
